Vitamin D may delay ageing processDate: 08/11/2007 08:48:50

Vitamin D may help to slow the ageing of cells and tissues, researchers have said.
The vitamin, which is manufactured in response to the skin's exposure to sunlight, is already thought to be associated with multiple sclerosis and rheumatoid arthritis.
Now, researchers at King's College London have revealed that people with high levels of vitamin D have fewer age-related changes in their DNA.
Lead researcher Professor Brent Richards said: "These results are exciting because they demonstrate for the first time that people with high levels of vitamin D may age more slowly than people with lower levels.
"This helps to explain how vitamin D has a protective effect on many age-related diseases, such as heart disease and cancer."
Henry Scowcroft, senior information officer at Cancer Research UK, said: "Several lines of evidence now suggest that this vitamin can help prevent disease and is necessary for good health, and this paper is another small piece in this particular scientific jigsaw puzzle."
However, Mr Scowcroft noted that overexposure to sunlight, the main source of vitamin D, is a "sure-fire way" to cause premature skin ageing.
"It's worth remembering that it doesn't take much time in the sun to make vitamin D, and always less time than it takes to redden or burn," he added.
